E-Z ...I highly recommend getting a new pump, new lines to the reservoir and a new reservoir... and well, might be a good time for 3 new belts too...
- remove the plastic mud guard from under the engine
- loosen the pully / pump tensioner
- unbolt the pump (take off your pulley too)
- take note of which line goes where and how they are routed
- get a pan to catch the fluid; remove the lines from the pump
- loosen the screw for the reservoir mount, pull the reservoir and the lines
- put yer old pulley on the new pump, replace with the new parts, fill the reservoir, turn the wheel lock to lock a few times and refill the reservoir to bleed the system
and...
USE ATF (automatic transmission fluid) NOT POWER STEERING FLUID
